Wowhead - Cahce issues

I've been having this problem too since last night. Site doesn't work in IE, FF, or Chrome. Disabled all browser addons. Deleted cache/cookies/history in all 3 browsers multiple times. Restarted computer multiple times. My computer is brand new and has no HDD problems.

This is getting REALLY irritating. I would be using a competitor's website if there were such a thing. FIX IT!!!
